0m and v on the disk or sheet 22, beginning at 26, and

the return end 27 is insulated from the convolutions or" the winding by a strip of mica 28. The ends of the heating winding are connected with binding posts 29 and 30 arranged in a binding post block 31 anchored in the body of the heating device, as clearly shown in Fig. 1. The binding posts 29 and 30 are connected with the wires of the cord conductor 16. .The current flowing through the winding 23 produces a high degree of heat which is conducted'to the metal plate or shell 17 on which the dining plate bears to be heated by direct contact and by radiation. If the dining plate is heated to the desired temperature the heating device on which the dining plate rests can be uncoupled from therdistributer by pulling out described the principle of operation, to-

gether with the device which I now con-. sider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v

1. An electric plate-warming device comprising a disk-like body formed of a top metal plate, a body ofinsulation under the plate, a heating conductor in heating relation to the plate, and a sheet of cork forming an insulating cushion for the bottom of the body.

2-. A plate-heating device comprising a shell, a body of insulating material disposed therein, a sheet of material disposed under the body and fastened to the shell and forming an insulator and cushion, a sheet of mica disposed between the body and top of the shell, a winding of wire on the sheet of mica, sheets of mica above and below the winding, and means for connecting the winding with a supply circuit.
